1) GUI.
K-Meleon hardly can be made more attractive as it main point is using Windows
native UI libraries.
But there are many ways to customize look and feel already.

2) Syncronizing Bookmarks.
What exact syncro options do you mean?

You already can import bookmarks from different browsers, use IE Favorites and Opera adr-files.

KM own Bookmarks are saved as html-file.
You can use it anywhere they are supported to move and store them. For example, online-services.
5 online bookmarking services are integrated in Twin - you can add viewed page to your online collection in a few clicks and get back to page (Personal Toolbar->LiveMarks)
I recommend to import your bookmarks.html into your favourite service (LinkaGoGo supports this as well as Diigo) and later add new bookmarks online instantly - using Twin's bookmarklets.

Finally, you can backup your Bookmarks (Bookmarks->Bookmarks Backup->Create Backup) as well as import FireFox Bookmarks or any collection stored in html-files by using Bookmarks->Bookmarks Importer.

Both Backup and Importer are KM extensions, included in Twin+ build by default.

HiRodo,Thank you very much.Can you make a provision to disable/enable individual plugins as in Firefox ,Chrome and Opera.So that we can reduce the bloat of the browser.can you kindly clarify me if i use Chrome option ,is there any chance to make the browser use more memory.Is there any trick to reduce the memory while using Chrome mode.

Easy switching extensions (that are usually macros) is possible at Preferences->K-Meleon plugins->Macro Extension.

While in Chrome tab KM uses slightly less memory than Chrome itself when opening the same page (but the difference is hardly greater than 5-10% or may be completely absent).
So I recommend use Chrome tab only for incompatible pages, not as a general rule)

To make build with other strings you have to make changes in these lines changing some of strings to yours preferred ones.

To make permanent change in working profile open about:config (Edit->Configuration->Browser Configuration), filter lines by 'useragent' keyword and edit some of settings by doubleclicking corresponding preference and editing the string.

2) This time I just use Ctrl+D (Add) & Ctrl+B (Edit) hotkeys respectively.
The default button in Twin works now as Edit/Submenu (that is bigger than one that you need but first 2 lines are exactly what you want)
So you can edit button code simply like this:

1) edit the file "defaults \ pref I10n.js [/ u]" but to save the changes, there is no change in the browser.
solo puedo hacer los cambios desde "about:config" I can only make changes from "about: config"

I am happy that the macro has been helpful for you.
And about the site " url-to-mp3.com " . If you want direct calling for it , i didn't find any browse extensions for it , the only way to send youtube link is the manual way or using (ajax+json+jQuery).

But i have some other ideas to embedded the site in youtube pages.
I will write macro for it & some others mp3 extract sites, and will post it in extension forum very soon .

I have started using the Groups and find it really great. Very fast and efficient . 1 small suggestion I would like to make is when you save the group that a drop down of the existing groups would show so that I could pick the group I want to save. This is mainly because I am using binserach and am changing the criteria every day.

Means no typo's then.

Come to think of it that would be nice to do the same for saving sessions. Although I am fast beginning to really appreciate the groups more so.

The prompt statement in the MacroLanguage does not permit multiple lines in the either of the message or title areas. Since it is possible to have many groups the statusbar might not hold all the names either. I have a listbox using Autoit, but it is also constrained by the length of the string of values sent to it.

I assume from your request that you wish to add one or more tabs to an existing group?

Save as Grp_Select.kmm with the all files option so Notepad will not add txt to the filename. Save the file to your macro folder. The macro folder is in the same folder as your k-meleon.exe file. Mine looks like C:\Program Files\K-Meleon\macros. Restart KM and you should have a new menu item in the Groups menu.

In groups I get a new entry under options showing "Retain Paths" which has a tick when I click on it. But not sure what it does or if it does anything?

This is what I would really like.

In sessions/options there is a section "delete Session" which gives you a drop down box to select which session you want to delete.

I would like the same thing in Groups but an added option to "Save As" with a drop down box so you can overwrite the name.

I can see groups being the no 1 function in the future for me. This feature is so powerful that I will be working towards not using Bookmarks or Sessions.

It really is an awesome feature and so simple to use. Yes and you can use 1, 2 or 3 groups at the same time and just delete the tabs you don't want. But the groups are still in tact if you don't overwrite the name
